Lawmakers submitted proposals on Thursday that would exempt Social Security and military retirement benefits from state income taxes, create a deduction for corporate dividends, and make it more difficult for the Legislature to approve future tax increases.

One senator introduced a bill that would allow Nebraskans to pay more taxes up-front, in exchange for an inflation-adjusted tax credit that would return the same interest as a 10-year Treasury bill.

Columbus Sen. Paul Schumacher says his proposal would allow the state to generate more up-front cash for road construction, where costs are constantly rising. He says the state could use those savings to pay interest on the tax credit.
